Thanks for you comments IDKB, much appreciated.
The exif details are as follows:
Exposure 30 seconds
Aperture f/14
Focal Length 17mm
ISO 100 I decided that the second of the two was the better one and kinda felt it was a little on the dark side so I have re-edited it to lighten it up. Only downside is the bridge light starburst's have suffered slightly. In photoshop I selected all the highlights and then chose select inverse, then feathered the selection by around 10 pixels but I still ended up with a weird effect around the bridge lights (not sure if what I did with photoshop was correct or not, still experimenting with it really). Still I think this edit is better than the first as you can see more detail in the bridge.
